New changelog entries:
* New upstream release candidate.
* Drop papersize-pre-html.patch: the "printing" operation here is only for
the purpose of extracting images, so all that matters is that the paper
size be consistent across the various tools that are invoked.

New changelog entries:
* New upstream release candidate.
* Build-depend on gsfonts, so that devpdf's U-* fonts are generated.
* Build-depend on poppler-utils, so that the new tests of mom examples
work.

New changelog entries:
* Restore text versions of meintro.ps, meref.ps, and pic.ps, broken in
1.22.3.rc1-1.
* Remove debian/groff.info; upstream's build system installs these files
by itself now.
* Use #! /usr/bin/perl for all installed Perl scripts, per policy 10.4.
* Remove dh_builddeb override to force gzip compression for groff-base;
most of the rest of the debootstrap-installed set needs xz nowadays so
that ship has sailed.
